Best 20000mah Portable Charger for fast-charging iPhones, iPads, and Samsungs / Androids
Anker PowerCore Essential 20000 PD USB-C 20-watt
Anker PowerCore Essential 20000 PD is our #2 pick as 20000mah USB-C PD power bank for fast-charging everything ranging from latest iPhone 13/12/11 series, XR/XS etc. and latest Samsung S/Note/A series phones, all Pixels, and latest USB-C iPad Pros and older iPads. The PowerCore Essential 20000 PD supports 20-watt USB-C PD charging and fast charges latest iPhones 13, 12/11 Pro, Pro/Max/SE2/XR/X/8/8+ etc. to 60% from empty in 30 minutes – all you need is a USB-C to Lightning cable. It also fast-charges latest iPad Pros as fast as the Apple USB-C PD charger. And yes, it also fast-charges all latest Samsungs including S22, S21 series, Note 20/10, and all Google Pixels from zero to 50% in about 30-35 minutes.
PowerCore Essential 20000 PD will fully charge most of the iPhones such as iPhone 13/12/11/XR etc. minimum four times (small screen iPhones 8/7/6s/6/SE2/ can be charged 6-7 times). The S22+, S22/S21 Ultra, S10+, S10 5G, and Note 10 can be charged about 3.5 times as they have much bigger batteries.
The large capacity of the powerbank is especially useful for charging iPads. It will give one full charge for the iPad Pro 2020 10.5 and it will still have enough battery to charge an iPhone 13 or 12/11 two times.
The PowerCore Essential 20000 PD itself gets charged in just 6 hours with any 18-watt PD charger such as Apple chargers that come with iPhone 11 Pro, 11 Pro Max, iPad Pro 2020/2018 chargers, all Pixel chargers, Samsung S20/Note series chargers or any Macbook USB-C chargers. If you plan to get a USB-C charger to fast-charge your iPhone 13/12/11/XR/8/8+/XS/X etc. to 50% in 30 mins, we recommend Anker PowerCore Nano , AmazonBasics 36-watt Dual PD port or Anker 36-watt Dual PD port . Dual PD port chargers are very handy as they can fast-charge BOTH your phone and PD powerbank at same time.
A handy but often overlooked freebie that comes with it is the USB-C to USB-C cable. These are required if you plan to fast-charge the power bank fast using a USB-C PD charger or if you plan to fast-charge Android USB-C PD phones such as Pixels. It also comes with a USB-C to USB cable for charging power bank with old non-USB-C adapters.

The power bank can deliver maximum 2.4 amps per port and has a 4.8 amp combined output. This means you can either charge four phones at once at regular charging speed (1 amp or same speed as Apple 5-watt iPhone charger) or charge two phones simultaneously at 2.4 amp fast charging speed.
This is our favorite tried and tested favorite solar-charging compatible power bank. Two input ports also allows you to plug-in two charging cables from solar-chargers for double the charging speed. For charging it in just 7 hours, you can use a dual-port charger such as Anker 24-watt dual charger.

Your wall chargers must be 2.4 amp/12-watt (you can use a charger such as Anker 24-watt dual charger) for fastest possible charging. Charging time using Apple iPhone 1-amp or 5-watt charger will be 24+ hours.

Please Note: It DOES NOT have USB-C PD which means it will NOT fast-charge latest iPhones 12, 11/XR/8/8+ etc. or Pixels to 50% in 30 mins.
A very handy feature is that EasyAcc 20000 USB-C will fast-charge all Samsung/LG/Moto/Mi phones to 50% in 30 mins through its green Quickcharge 3.0 USB port as it supports Quickcharge 3.0.
